Maximum location distance has, therefore, the fundamental limitations, not depending on the noise level. By the signal mean energy level of the order of some units of quanta discrete signal complies to the Poisson distribution (what explains the target flashing on locators screens). Expressions are got for time necessary for weak signals registration and for detection effectiveness taking into account the dynamics of the object. Targets identification by such signals is problematic due to equality of the signals mean values and the signals variance. The hypothesis is suggested that infrasounds anomalous influence is connected with the opposite phenomenon, e. i. with a very high quanta concentration by low frequencies of waves.</p>distance theoretical limitcorpuscular nature of small signalsPoisson distributionscintillationeffectiveness of objects detectionтеоретический предел дальностикорпускулярный характер слабых сигналовраспределение Пуассонамерцаниеэффективность обнаружения объектов
